IMPROVEMENT IN COUPLING SHAFTING AND RODS.

Specification forming part of Letters Patent No. 34,769, dated March 25, 1862.

' To @ZZ whom it may concern.-

Be it known that l, NELSON W. NOETHRUP, of the town of Greene, county of Chenango, State of New York, have invented a new and Improved Mode of Coupling Shafting and Rods; and Ido hereby declare that the following is a full and complete description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in inaking a coupling in two halves with ribs or flanges to hold the shafts in place, and also to take the place of a key or wedge to hold the coupling to the shaft to give them a joint m0- tion.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I make my coupling in two halves, as shown, Figures 2 and 3; B B r r, Fig. 2,arib or fiange lengthwise of the coupling to lit in a corresponding groove or slot u u in the shafts A A.

The other half, Fig. 3, I make with two cross ribs or flanges :1c :r to tit the grooves s s in the .shafts A A. The operation when closed together is to hold the shaft iirnily from being drawn apart.

I make the coupling tapered on the outside, as shown by the lines e e e, and have a sleeve or band that fits it driven on firm, as in Fig. l, G, in which is a set-screw; E, the seat below the surface, the point made to iit aeountersink drilled into the eouplin g after the band is driven on firm to prevent it from working loose by use.

What I claim as my invention is-e- The coupling made in two halves, as described, with the grooves, ribs, 0r flanges, and

band or sleeve and set-screw, combined and.

for the purposes set forth.
